Game Notes The Celtics begin a busy stretch of 5 games in 7 nights with this game vs the new look Philadelphia 76ers. Instead of the always hard to guard Andre Iguodala, Paul Pierce will now be matched up with Evan Turner.

The Sixers prize free agent from this summer, Andrew Bynum is out indefinitely with knee problems. For the first two games, the Sixers started a twin towers front line of Spencer Hawes and Kwame Brown. Brown strained a hamstring in Sunday's practice and is day to day and may or may not play in this game. If he can't go, it's possible that Hawes may slide over to center and Lavoy Allen may start at power forward. But, as with any preseason game, it's hard to tell who will start.

The Celtics' game notes project the same starting lineup as the last game, but again, in the preseason it's hard to tell until just before the game starts who will really be starting.

Both teams are coming off a close loss in over time with the Celtics losing to the Knicks and the Sixers falling to the Nets. Expect Doc to once again experiment with linups and also to play the young guys a majority of the minutes.
